摘要： A heart rate adaptive filter used in a physiology information sensing device is illustrated. The heart rate adaptive filter has a heart rate measuring device and a frequency configurable filter electrically connected to the heart rate measuring device. The heart rate measuring device can determine a heart rate or a heart rate signal according to a pulsatile signal sensed from an individual user. The frequency configurable filter can determine a transfer function thereof according to the heart rate or the heart rate signal and apply the transfer function to the pulsatile signal to generate an adaptively filtered pulsatile signal. Since the transfer function is determined according to the heart rate or the heart rate signal which has information of a characteristic frequency of the pulsatile signal, the signal-to-noise ratio of the adaptively filtered pulsatile signal can have improvement.

摘要： Systems, devices, processes, and algorithms for adapting and/or adjusting a reflectivity of a reflector in a radiation detector. The reflectivity can be changed by a reflectivity control signal that is generated based on an estimated count rate of events so as to adjust a probability of a photosensor detecting light resulting from the event via, for example, a scintillation event. By adjusting the probability, an energy resolution of the radiation detector can be optimized. The reflectivity of a reflector can be changed by changing a state of a thin film, a liquid crystal layer, or a suspended magnetic particle layer.

摘要： Systems, devices, processes, and algorithms for adaptively filtering a signal output from a radiation detector and adaptively sampling the signal. A count rate of events detected by the radiation detector is estimated by a processing unit. An RC time constant of the filter and a sampling rate of an analog-to-digital converter are adjusted based on the estimated count rate. Events are continuously detected by the radiation detector and counted by the processing unit while the adjustable parameters (the RC time constant and the sampling rate) of the filter and the analog-to-digital converter are adjusted on the fly (in real time) to optimize an energy resolution of the detected events, while reducing degradation due to pile-up effects and improving efficiency of the analog-to-digital converter. The filter can be implemented through analog filters, digital filters, or a combination thereof.
